How is a playing card's rank represented most elegantly in code?
* Should be a customized uint/an own type representing uints in the range of 2 through 14.
* void foo(Rank rank) { } // Accepts only the valid range
foo(0); // Error
foo(2); // Ok
foo(10); // Ok
alias J 11;
alias Q 12;
etc.,
foo(J); // Ok
foo(Q); // Ok
foo(B); // Error
